Google Workspace to Exchange Online migrations now support Gmail Filter to Outlook rule migration
Published Jul 06 2021 07:11 AM 16K Views

Previously, when you migrated content from Google Workspace (formerly G Suite) to Microsoft 365, a user could bring over their Mail, Calendar, and Contact information. While this did help reduce friction for users getting used to the new platform, it did not avoid the burden of re-creating all their email organization rules in Outlook. To address this, we have now added the capability to migrate Gmail filters to Outlook rules as a part of the standard migration offering!

With this feature you can now migrate Mail, Rules, Calendar and Contact data for all users and everyone is opted in by default.

Here are some of the conversions we support:

Conversions that are not supported

We do not currently support migrations of Categories from Google Workspace to Microsoft 365.

Additionally, if there are certain filters we are unable to process and convert, we mark these as bad items. And bad items from filters to rules migration do not negatively impact the DCS score of a job since that mechanism is more relevant for identifying data loss for the underlying data set (like Mail, Calendar and Contacts).

How to configure the feature

By default, the feature is enabled when you use New-MigrationBatch for Google Workspace migrations. If, however, you wish to disable the rule migration capability, you can do so by specifying the –SkipRules parameter via PowerShell.

In the screenshot below, you can see that there are now checkboxes for migrating Gmail Filters (to Outlook Rules) – which is checked by default. Simply un-checking the checkbox for Rules will skip migrating those items. Currently you need to do this via the Classic Exchange Admin Center; this change will be incorporated into the Modern Exchange Admin Center in the future.


Note: We do not have a way to reset rules once migrated, as is the case for any other data like Mail, Calendar or Contacts.

Try the feature out and give us feedback in the comments if the conversion was to your liking and what improvements we can make in the future!
